I would really like to put this motor in there transversely. I don't get that warm fuzzy with any of the transverse tranny's. The ones that are setup longitudinally are tried and true but that will add length to the car and I don't want to do that.

I think you can say they 65E-HD has been "tried and true"

you don't have to lengthen the car to put in a thn325 or thm 425 longditudal just lose all you trunck area.

I have, and they are far from reliable... The transmission can be made to hold the power, and they do work, but expect problems with everything else that you dont mod.

I go more by the "they are in junkyards" option more than the built option....

The TH425 setup I imagine would require a bit less "trick parts" as alot of the mods are more developed than the 65e... Also the 65e aftermarket is slowly disappearing due to GMperformance parts vaporizing slowly over the last year, at least in the FWD market.
